B Correct answer
Explanation

Oracle strongly recommends multiplexing control files by maintaining multiple copies on different disks. Control files contain critical database metadata and losing all copies can make the database unrecoverable. Alert logs, trace files, and snapshot files are important but don't require multiplexing to the same degree.
